It is assumed that $\displaystyle x$ and $\displaystyle y$ obey a law of the form $\displaystyle y = \ln(ax^2 + b)$. Pairs of values of $\displaystyle x$ and $\displaystyle y$ are recorded in an experiment and tabulated as follows:

By means of a straight line graph, verify that the law is valid.

Use your graph to estimate the values of $\displaystyle a$ and $\displaystyle b$

I am not very sure about changing the equation to linear form. Do I change $\displaystyle y = \ln(ax^2 + b)$ into $\displaystyle \frac{e^y}{x} = ax + \frac{b}{x}$?

Please help, any tips would be greatly appreciated, thank you.
